Abstract The aim of the present study was to investigate the occurrence of anti-Toxoplasma gondii antibodies and parasite DNA in backyard chickens bred in the metropolitan area of Recife, Brazil. In total, 212 serum samples were collected from 16 properties, and 12 backyard chickens were collected in the...
Background: Jatropha curcas L. (further referred to as Jatropha), as a rapidly emerging biofuel crop, has attracted worldwide interest. However, Jatropha is still an undomesticated plant, the true potential of this shrub has not yet been fully realized. To explore the potential of Jatropha, breeding and ...

La avicultura de traspatio es una actividad pecuaria de gran importancia en las comunidades rurales del país, caracterizada por la baja inversión requerida y por la facilidad para efectuarla; las especies más utilizadas son las criollas dado que se adaptan a las condiciones adversas para su crianza, e...
Background The aim of the present study was to assess the genetic diversity of Pantaneiro sheep, using microsatellite markers, in order to assist maintenance and management plans, enhance mating systems and reduce the inbreeding rate. A total of 127 animals were genotyped at eight microsatellite loci. Th...
In this paper, the degree of differentiation and morphostructural variability reached by the type of animal resulting from sustained directional selection, in addition to its implications for the emergence of a new sheep breed are analyzed. Twenty-five rams and 200 ewes from a sheep flock submitted to di...
BACKGROUND: Restricted space and close contact with conspecifics in captivity may be stressful for musk deer, as they are highly territorial and solitary in the wild. So we tested the effects of crowding on stress of forest musk deer (Moschus berezovskii) in heterosexual groups, using fecal cortisol anal...

A amamentação é uma prática que envolve relação de ensino e aprendizado entre gerações. Portanto, as mulheres que a experienciam necessitam de modelos que advém das suas mães e/ou avós maternas. Para tanto, tivemos como objetivos apreender as representações sociais sobre amamentação de mul...
Background: Haploid plant material is considered as recalcitrant to organogenesis, propagation, and maintenance in vitro. However, sugar beet (Beta vulgaris L.) breeders utilizing doubled haploid (DH) technology in their breeding programs indicate that sugar beet haploids may be cultured in vitro as well...
New fruit varieties are needed to satisfy consumers, and the industry is facing new challenges in order to respond to these demands. The emergence of genomic tools is releasing information on polymorphisms that can be utilized to expedite breeding processes in species that are difficult to breed, given t...
En el presente trabajo se presentan diferentes posturas éticas sobre la inseminación homóloga. Los distintos juicios de los diversos autores varían de acuerdo con sus presupuestos antropológicos. Por este motivo, la exposición se organizó partiendo de uno o más representantes de las corrientes fi...
